Quoted from zacaj:fast coil pulsing?
Maybe. I do like to play fast. How many spins do you get off one of your spinners? I'm getting 40-50 and only the last 8 or so are chimed
*problems (my bad, maybe it is more readable now, I edited it to fixed the typo now)
What I meant was the circuit boards have trouble keeping up. They take it through the switch matrix and wiring back to the boards (and also I'm sure the code only checks for switch hits every so often (milliseconds) but it sounds like you're not having that kind of issue since it is scoring) and then the power to strike the chimes has to be sent back out through the driver board, MEANWHILE, an EM spinner is just a switch to the power line of the 10 point (or whatever) relay, which itself is just a power switch to the reel and coil.
SS:
Switch press -> Wait for board to accept -> Board runs through code to go to function of what that switch does -> Adds score -> Tell driver board to power chime -> Driver board powers chime.
The score adding and chime triggering are likely not in parallel since they're probably only fractions of a millisecond apart - why bother? Granted, this is all done incredibly quickly even with the technology at the time (fractions of milliseconds or at least milliseconds)- BUT, then you're ripping that spinner so incredibly fast on top of that, it can't keep up.
I know Bally and Gottlieb games (and probably Williams too) will put everything in a "queue" to be done, so like if your ball hits 5 switches before the board can get through and score them and play a sound for them - you will still receive your points properly. Like if you go in and touch a playfield switch incredibly fast you can create a repetitive line of scoring for each of the those presses even after your pressing is over. But if they did for a chime spinner, it would sound really silly for it to still be going with the spinner stopped, so they likely don't keep the sound queues in this "note to self: do later" line.
EM:
Hit spinner -> Powers 10 point relay -> Powers score reel and chime in parallel
No waiting for much - no reasonable delay, just the 299,792,458 meters per second electricity travels through wire (but read next sentence) & the split second activations of EM relays. Of course the chime coils as well, but the electricity speed + coil speed is something that both the EM and SS share.
Unless other owners of this SS title have different experiences, I'd say your game is fine!
